The Las Vegas Raiders’ abysmal season has taken yet another turn for the worse.

The team placed Pro Bowlers Darren Waller (hamstring) and Hunter Renfrow (oblique) on injured reserve Thursday.

The moves will shelf Waller and Renfrow for at least the next four games. Waller had already missed the previous three with his injury.

Waller was labeled as a game-time decision Sunday but didn’t suit up. He practiced on Wednesday in a limited role.

He reportedly re-aggravated the injury, however, leading to the decision to place him on IR. Renfrow missed two games earlier this year with a hip injury.

Waller has struggled the last two seasons after becoming one of the league's premier tight ends almost overnight.

After struggling to stay in the league for several years due to drug addiction, Waller became a "Hard Knocks" star and turned that into a 90-reception, 1,145-yard season in 2019. He finished in third place for the Comeback Player of the Year Award.

The 2020 season is what really put Waller in the upper echelon of tight ends, though. He caught 107 passes, nine of them for scores, for 1,196 yards, and was named to the Pro Bowl.

In Week 1 of 2021, he looked well on his way to repeat the previous two seasons with 10 catches for 105 yards and a touchdown. However, in 16 games since, he has just 71 catches for 840 yards and three touchdowns.

Since Week 2 of 2021, he has just three games of at least 70 receiving yards. He missed five of the Raiders’ last six games last year with a knee injury.

Renfrow burst onto the scene last season when he caught 103 passes for 1,038 yards and nine scores. In his previous two NFL seasons, he had 105 catches for 1,261 yards and six TDs combined.

In six games this year, he's made only 21 catches and has not scored a touchdown. He's put up just 192 receiving yards.
